Description I Shank irons;providing. means for supporting ashoe structure at the outer edges of, the shank-arch have been employed. 7 Flanges rigidly upset, as a continuous feature'ofoonstruction', haveextended over the inseamsof ,q shoes to afiord a rigid support therefor. The bulkinessfofsuch constructions has proved objectionable for the reasons that special eshankironsq-have been required for every variation andchange in the width'of shoes. Thus? narrow, shank irons, medium shank irons and wideshank irons; have had to, be provided. 7

. rln thepresent inventionthe above mentioned; objections have been overcome by constructlngshank irons, as seen in the draw- Figure l is a;viewrof the; llnder s derof at;

rings, in two sections or halves, which overlap va-riety of total widths.

overcome by providing a shank iron having niov able over-lappingsections' 11 and 12. The sections 11 and 12 are slidably connected, ,the; section 11 being provided with curved slots 13, while the section l2is'p'rovided'with 7:,

headedstuds 14;- the shanksof which extend N 7 throughthe-slotsl r Fi ureeis a detailedview of thesh nk r By observation of Figures 4 and 5-, it will 7 be seenthat the sections 11 and 12 may he laterally adjusted and so accommodate the so of a Shoe at the shank-arch thereof. 1 To supportthe' said inseams; the said sec itions are each provided with a se'riesoi up- ;As shown in Figures 2and 8 of the drawingsflhe lugs ;l5extend .under the insea-ms l6. Itwill also be-observedthat the lugs 15 are relatively na rrow and spaced apart." This Thefirst-mentioned objection has @been o standing and laterally extending lugs 15. 85 I ;c nst12uct 9 1:p vid s od a f o hevs t q I 99' 11 and 12 which are ridged at the outer edges adjacent said lugs. These ridges 23 fill in the spaces next to the edge of the inseams, which spaces are usually neglected or left unfilled by the cork filler when same is being placed over the shank iron in shoe construction. The ridges also serve to augment the rigidity of the shank iron sections.

As seen in the drawings, the sections are provided at the advanced end of the shank iron with forward-reaching lugs 17. These in service reach forward, as is seen best in Figure 2 of the drawings, and support the inseams 16 up to and adjacent the bending line or moment of the shoe.

As shown best in Figure 3 of the drawings,

the shank iron rests upon the fillet 18. This fillet 18 may be constructed of any material, preferably wood. A shoulder 19 is provided therein to form an abutment for the forward endof the shank iron.

As will be seen best in Figure 2, thefillet 18 is formed to shape the rear edge 22 ofthe molded portion of the sole 20, where the same 3:, is extended rearwardly in accordance with the style of the shoe adopted.

It is obvious that when thus arranged, the abrasion on the sole members formerly objected to is avoidedall abrasion being now received by the fillet 18. The'fillet 18"is held firmly in position by the sole 20, the shank iron and the filler 21 with which the'shoe is end of the shank member, and-to provide a depression between the shank portion and the ball portion of the shoe, caused'by the shoulder 26. This depression forms a natural rest or drop into which the metatarsal structure, or bones forming same, drop.

From the foregoing it will be seen that the objections cited have been avoided by the present construction. I Y

Claims:

1. A shoe construction having an insole and upper secured thereto by inseams extending under the shank-arch of the shoein spaced relation, a shank iron comprising a plurality of pivotally connected members adapted to rest upon said insole between said inseams and to be expanded'laterally to rest against the edges of sa1d lnseams, andmeans' integral with said members for extending over sa d 111- seams'to support the same in service.

. 2. A shoe construction having aninsole-and upper secured thereto by inseams extending under the shank-arch of the shoe in spaced relation, a shank iron comprising a plurality of pivotally connected members adapted to rest upon said insole between said inseams and to be expanded laterally to rest against the edges of said inseams, and means integral with said members for extending over said inseams to support the same in service, said means embodying a plurality of laterally upset and extending lug members adapted to extend over said inseams, said members being spaced apart.

v 3. A shoe construction having an insole and upper secured thereto by inseams extending under the shank-arch of the shoe in spaced relation, a shank iron comprising a plurality of pivotally connected members adapted to 7 rest upon said insole between said inseams and to be expanded laterally to rest against the edges of said inseams, and means integral withlsaid members for extending over said inseams to support "the same in service, said means embodying a plurality of laterally upset and extending lug'members adapted to extend over said inseams, said members being spaced apart, the said lugs at the forward end of said'shank iron members being inclined to underliethe said inseams at the forward ends thereof. 7

4-. 1%. shoe construction having an insole and upper secured thereto by inseams extending under the shank-arch of the shoe in spaced relation, a shank iron adapted to rest on the said insole between said inseams, said shank iron being adapted for lateral adjustment to accommodate differences inv spacings between said inseams, and a rigid fillet adapted to receive the forward end of said shank iron memhere to protect the wear-sole of the shoe from abrasion thereon. I

-5. In a shoe construction as characterized, a shank iron comprising a plurality of metal plates slidably connected for lateral extension and adjustment, the saidplates having a plurality of laterally extended lugs for extending over an adjacent inseam in service, said lugs being spaced apart to permit said plates to accommodate the curvature'of the shank portion of a shoe so constructed.

6. Ina shoe construction as characterized, a shank iron comprising a plurality of metal plates slidably connected for lateralextension and adjustment, the said plates having a plurality of laterally extended lugs for extending over an adjacent inseam in service, said lugs being spaced apart to permit said plates to accommodate the curvature of the shank ortion of a shoe so'constructed two or more of said lugs at the forward end of said plates being disposed in angular relation to the axis of said shank iron to reach'forwa'rd thereof to cover said inseams adjacent the ends thereof.
